WCF dynamic configuration of security

Hi,

I want to design a wcf service contract that send sometime the messages encrypted and signed (transport security) and sometime send the messages without security.

Solution 1: create 2 services, one with transport security enabled and the other without security.

Solution 2: create 1 service without security and manually encrypte the message (at application level).

Solution 3: a better solution...?

Regards,

Eric
